It will be understood that the above described constructions shall serve as examples only, and that combinations of the various arrangements will fall within the scope of the invention, and that variations of details are possible to comply with peculiarities of the vehicle in connection with which the device is to be utilized.

I declare that what I claim and desire protected by Letters Patent is:

1. In a vehicle, a transverse axle; wheels carried by said axle; a vehicle body; a first set of struts bearing with their upper ends on the underside of said vehicle body at substantially its longitudinal center line and bearing with their lower ends on generally the longitudinal end portions of said axle; and a second set of struts hearing with their upper ends on the underside of said vehicle body at points at a substantial distance from the longitudinal center line of the vehicle and bearing with their lower ends on said axle at substantially the longitudinal center thereof.

2. In a vehicle, a transverse axle; wheels carried by said axle; a vehicle body; a first set of struts; pivot means connecting the upper ends of said struts to the underside of said vehicle body for rotation about a vertical axis, the said pivot means being disposed at the longitudinal center line of the vehicle; means for connecting .the lower ends of said struts rigidly to generally the longitudinal end portions of said axle; a sec- 0nd set of struts rigidly connected at their upper :ends to the underside of said vehicle frame at points at a substantial distance from the longitiudinal center of the vehicle; and pivot means connecting the lower ends of the latter struts to said axle for rotation about a vertical axis, the latter pivot means being disposed at the longitudinal center of said axle and in vertical alignment with'said pivot means of said first set of struts. 3. In a vehicle an arrangement constructed in accordance with claim 2 wherein each of said pivot means is constituted by a stationary pivot pin'and bearing sleeve rotatable about said pivot pin and wherein the corresponding set of struts is secured to said sleeve.

4. In a vehicle, a transverse axle; wheels car- ,ried by said axle; a vehicle body; a single spindle disposed vertically and having its upper end rigid- 1y secured to the underside of said vehiclebody; .means for rotatably securing the lower end of said spindle to the longitudinal center of said axle; a first set of struts having its upper ends rigidly connected to the underside of said vehicle ,body at points at a substantial distance from the longitudinal center of the vehicle and havin its lower ends rigidly connected to said spindle in proximity to said securin means for the lower end thereof; a second set of struts having their lower ends connected to said axle at generally the longitudinal end portions thereof; and 00- operating bearing means disposed on said spindle 'in proximity to the upper end thereof for securing the upper ends of said second set of struts to said spindle for revolving about the spindle as 7 'axis of rotation.

4 its longitudinal center line and bearing with their lower ends on generally the longitudinal end portions of said axle; and a second set of struts bearing with their upper ends on the underframe of said vehicle body at points at a substantial distance from the longitudinal center line of the vehicle and bearing with their lower ends on said axle at substantially the longitudinal center thereof.

6. In a vehicle, a transverse axle; wheels carried by said axle; a vehicle body; an underframe fixedly mounted on said vehicle body; a single spindle disposed vertically and having its upper end rigidly secured to the underframe of said body; means for rotatably securing the lower end of said spindle to .the longitudinal center of said axle; a first set of struts having its upper ends rigidly connected to the underframe of said vehicle body at points at a substantial distance from the longitudinal center of the vehicle and having its'lower ends rigidly connected to said spindle in proximity to said securing mean for the lower end thereof; a second set of struts having their lower ends connected to said axle at generally the longitudinal end portions thereof; and cooperating bearing means disposed on said spindle in proximity to the upper end thereof for securin the upper ends of said second set of struts to said spindle for revolving about the spindle as axis of rotation.

'7. In a vehicle, a transverse axle; wheels carriedby said axle; a vehicle body; a single spindle disposed on theunderside of said vehicle in the longitudinal center of said axle; a first set of struts having its upper ends rigidly connected to said vehicle body at points at a substantial distance from the longitudinal center of the vehicle and having its lower ends rigidly connected to said spindle in proximity to aid securing means for the lower end thereof; a second set of struts having their lower ends rigidly connected to said axle at generally the longitudinal end portions thereof; abearing member disposed on said. spindie in proximity to the upper end thereof; and a bearing sleeve rotatably cooperating with said bearing member, the said bearing sleeve being connected to the upper ends of said second set .of struts so that the later struts areadapted for revolving about the spindle as axis of rotation.

8. In a vehicle, a transverse front axle; a transverse rear axle; wheels carried by each of said axles; a vehicle body; an underframe fixedly mounted on said vehicle body, the said. under.- frame havinga front portion and side portions; a perch. extending at the longitudinal center of said .vehicle,-and connecting the said front and rear axles; asingle spindle disposed vertically and having its upper end rigidly secured .to the underframe of said body; means for rotatably securing the-lower end of said spindle to the longitudinal center of said front axle; a first set-of struts connecting the said perch to the side portions of said underframe; a stay connectin the said perch at its front end to the front portion of said underframe; a second set of struts having their lower ends connected to said front axle at generally thelongitudinal end portions thereof; and cooperating bearing means disposed on said spindle inlproximity to the upper'end thereof for securing the upper ends of said second set of struts to said spindle for revolving about the spindle as axis of rotation.

9. In a vehicle, a transverse front axle; a transverse rear axle; wheels carried by each of said axles; a vehicle body; an underframe fixedly mounted on said vehicle body, the said underframe having a front portion and side portions; a perch extending at the longitudinal center of said vehicle, and connecting the said front and rear axles; a single spindle disposed vertically and having its upper end rigidly secured to the underframe of said body; means for rotatably securing the lower end of said spindle to the longitudinal center of said front axle; a first set of struts connecting the said perch to the side portions of said underframe; a stay connecting the said perch at its front end to the front portion of said underframe; a second set of struts having their lower ends connected to said front axle at generally the longitudinal end portions thereof; cooperating bearing means disposed on said spindie in proximity to the upper end thereof for securing the upper ends of said second set of struts to said spindle for revolving about the spindle as axis of rotation; and bracings for said stay, the said bracings extending laterally from said stay to said underframe.
